About this study
Prospective, nonrandomized, single-center, comparative study to define if right ventricular (RV) contractile reserve assessed by exercise CMR helps to improve the differential diagnosis between pathological and physiological remodeling of the RV; ie. arrhythmogenic right ventricular cardiomyopathy (ARVC) and athlete's heart.
Read the detailed description
Comparison of the RV contractile reserve in 4 groups of patients: Arrhythmogenic right ventricular cardiomyopathy (ARVC) patients; endurance athletes with a dilated RV, endurance athletes with normal RV, untrained subject with normal RV.
Patients will come to the hospital for 3 visits (3 half days):
- Visit 1: clinical evaluation, rest ECG, rest echocardiography, cardio-pulmonary exercise test.
- Visit 2: exercise echocardiography, holter ECG monitor (48 yours)
- Visit 3: rest CMR and exercise CMR (ergocycle)
- Being tested
- Cardiac exercises and tests
- Keywords
- ARVC, Athlete's heart, exercise, CMR, RV contractile reserve
- Medical subject headings
- Arrhythmogenic Right Ventricular Dysplasia, Motor Activity

Why it stopped: Inclusions were in February 2024, following the replacement of the MRI scanner in which the stress-induction system had been installed. To date, technical tests were conducted but failed to establish a reliable system.

Results and safety
The study was stopped early (reason given: Inclusions were in February 2024, following the replacement of the MRI scanner in which the stress-induction system had been installed. To date, technical tests were conducted but failed to establish a reliable system.). Results are not available in the source record.

Questions about this trial
What is this clinical trial studying?
A study testing Cardiac exercises and tests in people with Arrhythmogenic Right Ventricular Cardiomyopathy, run by Rennes University Hospital at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 15 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Inclusions were in February 2024, following the replacement of the MRI scanner in which the stress-induction system had been installed. To date, technical tests were conducted but failed to establish a reliable system.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evolution of right ventricular ejection fraction (RVEF) assessed with CMR during exercise (time frame: Through study completion, an average of 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2026; AzTrials last refreshed its copy on 7 Nov 2026.
